Application September 24, 1934, Serial No. 745,324 Renewed March 12, 1936 1 Claim.

This invention relates to a novel accessory in the form of an attachment cooperable with the lid and glass top of a percolator and expressly designed to serve as a means for maintaining said glass top against accidental displacement.

By way of introduction it is to be pointed out that in the majority of constructions the caplike glass top of a percolator is generally provided with a rim having diametrically opposed projections which serve to hold the glass top in place after it is inserted in lid and turned slightly. In most instances the lid is formed With a central opening having a depending annular flange equipped with diametrically opposite clearance notches to accommodate the projections whereby to permit the projections to be held in place by the flange. It is a matter of common knowledge, however, that wear and tear of these parts soon permits rotary shifting of the glass top and it is frequently displaced, resulting in breakage and other damage.

The purpose of the present invention is to provide a resilient wire device in the nature of a clip which can be attached to the button-like 25 projections on the glass top and which cooperates with the flange in a more satisfactory manner to satisfactorily hold the glass top in place and against accidental displacement.

Other features and advantages will become more readily apparent from the following description and drawings.

In the drawings:

Figure 1 is an elevational view of the wire retaining device or clip showing the manner in 35 which it is associated with the glass top and hinged lid of a percolator.

Figure 2 is a bottom plan view of the structural assemblage depicted in Figure 1, the section being on the plane of the line 2-2 of Figure 1.

Figure 3 is a vertical sectional view taken approximately on the plane of the line '33 of Figure 1.

Figure 4 is a section on the vertical line 44 of Figure 1.

Figure 5 is a perspective view of the wire from which the retaining clip is bent or fashioned.

Figure 6 is a perspective view of the retainer or clip per se.

Referring now to the drawings by distinguishing reference characters I call attention first to Figure 1 wherein the percolator is denoted by the numeral 1 and the hinged lid is indicated at 8. The glass top, which is conventional, is denoted by the numeral 9. The customary rim ID at the bottom of this glass top is formed with the usual diametrically opposed button-like projections H. Under ordinary circumstances these are adapted to be placed through the clearance notches I2 formed at diametrically opposite points in the depending circular flange I3 carried by the lid. That is to say, the rim [0 fits telescopically down through the opening and against the flange, the projections of keepers ll being placed through the notches I2 and then turned so as to be held against the lower edge of the flange. As before stated, however, these parts frequently become loose and this results in a recurring displacement of the glass top. Therefore, I have evolved and produced requisite simple and economical means to guard against such accidental displacement of the glass top. This means may be described broadly as a retainer and it is in the form of a resilient Wire clip M of the type shown in Figure 6. This clip may be formed from a single length of wire l5 (see Figure 5). It is bent between its ends to form a coil spring as at I6 and to further provide a pair of duplicate adapter arms or branches I'I. These terminate in upbent eyes l8 which are adapted to snap over the projections H (see Figure 4) so that the eyes themselves will serve as retaining elements and engage beneath the edges of the flange as shown in Figure 4 to prevent displacement of the glass top. It is obvious that the wire must be non-corrosive and sufliciently resilient to enable it to be conveniently snapped into place and confined primarily within the limitsof the glass top itself.

It is evident from the foregoing description that the novelty and invention resides only in the attachment or retaining clip illustrated in Figure 6. Fundamentally this comprises retaining elements l8 to resiliently snap on and surround the stock lugs on the glass top whereby topermit these pieces l8 to serve as check elements or stops for holding the glass topin place. Stated otherwise the principal novelty is in the features l8 with some means for attaching them together resiliently and holding them on the lugs so that they merely enlarge the lugs and provide a more satisfactory means of avoiding displacement of the glass top if and when the lugs or flange are spread or become worn. Thus it will be seen that novelty resides in these stopelements I8 which embrace the lugs and which are attached together through the instrumentality of resilient arms I! forming a connective element and which 55' arms themselves are preferably associated with a spring or coil I6.

In practice the device is simply snapped on to the lugs after the glass cap is in place and this is done by swinging the lid 8 to open position.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.

Minor changes in shape, size, and rearrangement of details coming within the field of invention claimed may be resorted to in actual practice, if desired.

What is claimed is:-

As a new article of manufacture, a retaining clip'for a percolator top comprising a length of wire provided at opposite ends with loops fashioned to embrace existing lugs on the percolator top, said wire being bent between its ends to define a centrally disposed coil spring with laterally extending overlapping arm portions normally urged by said coil spring in a downward direction.
